Plastic-fantastic!
'No Biggie' are a stylish pair of sunglasses. The fit is perfect and very comfortable. The dark, smokey shade of the lenses give you a nice protection from the sun, although they can be a bit difficult to see through, if the sun is high in the sky.
The temples are a bit tight in the hinges, maybe they will get loser with wear and time, we will see.
Overall, I am very happy with my purchase and would buy other styles of Le Specs in the future.
